Web12 jul. 2024 · Current U.S. nuclear reactor designs require a stronger concentration (enrichment) of the U-235 isotope to operate efficiently. The uranium hexafluoride gas produced in the converter facility is called natural UF 6 because the original concentrations of uranium isotopes are unchanged. Uranium enrichment Web12 apr. 2024 · In a process called multinucleon transfer, two isotopes exchange protons and neutrons, resulting in nuclear fragments with different isotopes. The researchers identified uranium-241 and measured the mass of its nuclei using time-of-flight mass spectrometry. Theoretical calculations suggest that uranium-241 may have a half-life of …
